Compatibility to pydantic >= 2

Open bolau opened this issue 1 year ago • 6 comments

Hi, I use fastapi and pydantic-cli in the same project. I would like to use pydantic in a recent version, but pydantic-cli restricts it to <2 in the requirements.txt. Do you plan to accomodate the newer versions at some point? Best, Boris

Hi!

I'd like to second this ask. It looks like there is something in #54 by the dependabot, though it appears to have failed CI and nothing was done after (It makes sense that this would fail, pydantic 2 has many breaking changes). I was looking at this tool as it would do what I want typer to do (to turn pydantic models into flags). Is there any way I could help @mpkocher?

Best, Adrian

I'll look into supporting Pydantic 2.

What is the minimum version of 2 (>= 2.5.x?) that should be supported?

@mpkocher 2.4.0 seams to be the first minor release with new features, however I see no reason to just support all of v2. So far most of the changes aren't big from what I can tell (in terms of user experience, and in terms of breaking changes I think there are none). You might find the improved deprecation notices in the more recent releases to be helpful in developing though

@acederberg you can just use the v1 namespace https://github.com/pydantic/pydantic/issues/5771

@bolau and @acederberg Perhaps you should considering following the effort in the pydantic-settings repo for a Pydantic CLI interface that uses Pydantic 2.

It does look like that project has different requirements/goals than pydantic-cli. However, a CLI interface in pydantic-settings does look promising and it could have a larger user base and better documentation than pydantic-cli.

@mpkocher are you planning on adding support for pydantic - 2 in the near future?

Support for Pydantic v2 has been added.

This has created several backwards incompatible changes. The new API should be more ergonomic and there should be less of a friction point between non-subcommands and subcommand tools.

There's also been some build issues with moving to pyproject.toml that have been resolved. Installing from pypi should work as expected now.
